For the hydraulic cylinder, the main factor affecting its service life is friction. Of course, all machinery will produce friction during operation, and friction is a key factor affecting the service life of the equipment. For example, after the engine is started, there will be a lot of friction, such as the friction between the piston ring on the cylinder block and the cylinder arm surface.
Hydraulic cylinder manufacturers believe that, in fact, for hydraulic cylinders, the main factor affecting their service life is friction. Of course, all machinery will produce friction during operation, and friction is a key factor affecting the service life of the equipment. For example, after the engine is started, there will be a lot of friction, such as the friction between the piston ring on the cylinder block and the cylinder arm surface.
In addition, there is friction between the crankshaft and the bearing bush. The manufacturer explained that under normal circumstances, after the hydraulic plunger pump rotates, there will be friction between the plunger and the cylinder bore, and there will be friction between the valve plate and the cylinder body. Nowadays, in order to reduce the effects of friction, oil is usually used for lubrication where friction will occur. These lubrication actually belong to the gap lubrication.
The manufacturer explained that these lubrication measures mainly include three aspects, namely lubrication, sealing and force transmission. In the gap lubrication, it also includes different lubrication states, in which the mechanical sliding between metal and metal, and the actual working conditions are different. The so-called lubrication actually refers to wrapping a layer of oil film on the surface of the metal substance, so that when the metal and the metal move in a small gap, there is no contact between the two.
If the lubrication treatment is not carried out, then the two are likely to produce very serious friction, and then seriously affect its service life. According to the manufacturer, these frictions will not only increase the burden on the engine, but also accelerate the wear of the working surface of the parts. In severe cases, the heat generated by friction will also burn the working surface of the parts and cause the engine to fail to run.
In fact, the main function of lubrication is to reduce the degree of friction between metal substances when the equipment is working, so as to improve its stability and durability. Manufacturers remind, in the lubrication, but also need to combine the actual situation of regular lubrication, in order to ensure the lubrication effect.
